Saracens confident injured Mako Vunipola will be fit for World Cup

• Loosehead prop tore his hamstring in Champions Cup final• England’s first warm-up match is against Wales on 11 August

Mako Vunipola’s season is over but the Saracens director of rugby, Mark McCall, is confident the loosehead prop will be fit for England’s World Cup campaign.

Vunipola suffered a hamstring injury during the first half of Saracens’ European Champions Cup final win over Leinster last Saturday, hobbling off at the same time as his teammate and the tighthead prop Titi Lamositele. It was only Vunipola’s second appearance after recovering from an ankle injury sustained during England’s Six Nations victory over France, forcing him to miss three subsequent matches including the decisive defeat by Wales.
